New 2" Output Shaft
Heco is pleased to announce the introduction of a new 2" straight keyed output shaft. This new shaft, designated Code 6, is a available on all Model 16 reducers, and can ship from Heco based upon our standard lead-time of 4-6 weeks. There will be no additional charge when choosing this shaft option. Code 6 is a 2.000" Straight Keyed, and there is no additional charge for this option.

New Auger Output Shafts
Heco is pleased to announce the introduction of two new output shaft configurations for our Model 16 series of Reducers. The new shafts are used in standard auger configurations and make the HECO Model 16 a very desirable alternative for these types of applications. Code 7 is a 2.545" Straight Keyed Shaft w/ Cross Drilled Hole, and the additional charge for this option is $88. Code 8 is a 2.000" Hex w/ Cross Drilled Hole, and the additional charge for this option is $125.

Replacement Planet Gears and Planet Bearings
Part numbers 15005D (Model 16 planetary gear) and 151130 (Model 16 planetary bearing) are no longer available. These parts have been replaced by part numbers 15006NR (New Model 16 planetary gear) and 151150 (New Model 16 planetary bearing). The "new" style gears and bearings have been used for the past six years in all revision 4 series Model 16, Model 16D, Model 20D, Model 50D and Model 52T reducers. The "new" gears and bearings will work in revision 3 reducers, but they must be purchased and installed in sets (one 15006NR and two 151150), since the old bearings are not compatible with the "new" gears and the "new" bearings are not compatible with the old gears. It is very difficult to discern between the old and "new" style visually because there is only a 1mm differentiation.

Definition? Design Life/Service Factors
The torque rating and radial load capacity shown for all Heco gear boxes are for a service factor of 1.0. For all other service factors the gear box should be derated by the service factor from the table below. 1.0 - Mixers and Agitators with uniform density, Uniform Fed Conveyors (belt and auger) 1.2 - Heavy Duty Conveyors (belt and auger), Car Wash 1.4 - Booms, Cranes, Swing Drives, Heavy Mixers, Wheel Drives, Shakers 1.7 - Rolling Mills, Digging Augers, Wheel Drives Heco Rated Torque ÷ Service Factor must be equal to or greater than Applications Torque Heco Rated Radial load ÷ Service Factor must be equal to or greater than Applications Radial Load Input Torque * Gear Ratio = Output Torque Input Speed ÷ Gear Ration = Output Speed High torque and low speed or low torque and high speed will give the maximum life, expect a reduction in gear box life for combined high torque and high speed applications. The information on service factors is provided as a guide in preliminary selection of the gear box. The service factor is based upon the character of load, load application and load duration, and must be determined by an engineer familiar with the particular application. Peak loading may exceed the values shown if the nominal torque is well below the continuous torque rating, contact Heco Inc., for Miner’s Rule Calculation. Application analysis and customer testing is strongly recommended.

Instructions - Disassembly
Disassembly Instructions Warning: Standard safety practices must be followed during the procedures described herein. Eye protection is mandatory. Clean exterior of unit prior to attempting disassembly. Remove unit to clean work area. 1) Clamp mounting flange in vice shaft down taking care not to damage output shaft surface. 2) Remove pipe plug (13 or 23) from case and drain oil from unit. Retain oil for analysis. 3) Remove remaining two pipe plugs in housing (12) and motor adapter (22). 4) Remove hydraulic motor and examine for failures. Our experience indicates that motor failure is the most common cause of reducer failure. 5) Remove sungear (25) 6) Remove eight bolts (24) from motor adapter (22) (fig. 1) Note: Code 6, 2/4 SAE-C motor adapter, remove nuts from studs (24) 7) Remove motor adapter (22) from internal gear (21). 8) Lift internal gear (21) from housing (12). 9) Remove O-rings (14) from internal gear (21). 10) Remove retaining ring (9) from grove in shaft (7). Note: (9) is a wirelock retaining ring that retains the planet carrier assembly (2) on the output shaft (7). This locking ring must be pried out of the locking ring groove to remove the planet carrier assembly (20). This is typically accomplished by inserting tow long screwdrivers between the planet gears and carefully working the wirelock out of the locking groove. (fig. 2 & 3) 11) Lift planet carrier assembly (20) from shaft (7) 12) Bend tab on lock washer (18) away from lock nut (19). 13) Using a spanner wrench or HECO tool #19150, unscrew lock nut (19) and remove lock washer (18) and keyed washer (17). (fig. 4) 14) Take unit out of vice and turn it over. Remove six cap screws (1) from seal carrier (3). (fig. 7) 15) Remove seal carrier (3) from housing (12). 16) Remove O-ring (6), quad and backup ring or high pressure seal (4 & 5) and shaft seal (2) from seal carrier (3) and discard. (fig. 8) 17) Support housing (12) with output shaft down and press shaft (7) out of housing from input end of shaft. Note: Shaft may come out with bearing cone (16) attached. Remove bearing cone carefully to avoid damage to shaft. 18) Carefully drive bearing cups (11 & 15) out of housing (12). 19) Remove two retaining rings (3) from ends of planet pins (29). (fig. 9) 20) Support planet carrier (20) spline side down and drive planet pins (29) out of planet carrier (20). (fig. 9 & 5) 21) Remove planet gears (28) and thrust washers (26) and planet carrier. (fig. 9) 22) Remove planet bearings (27) from planet gears (28). 23) Examine brass thrust plug (8) in end of shaft (7). (fig. 2) If wear is apparent, remove by inserting a 1/4" self taping screw and jacking the plug out of the shaft. 24) Clean and examine all parts for wear or failure.

Product - High Pressure Seals
High Pressure Shaft Seal HECO has introduced high pressure shaft seals for all models. This seal is made by Parker and offers the advantage of increased case pressure when using a bearingless Char-Lynn motor or any hydraulic motor that has been modified to allow case flow to lubricate the gear unit. This seal has been particularly effective in applications where the gear unit is operating vertically with the shaft down. In these applications the high pressure seal will allow more shaft deflection when when the shaft is operating in a high side load condition.

Product - Custom Configurations
HECO planetary speed reducers adapt to most hydraulic motors and applications, but if you have a custom application requiring a special shaft or mounting adapter, HECO engineers will work with you. HECO also welcomes custom OEM engineering work. Consult your local distributor for assistance.

Definition? Continuous Torque Rating (lb-in)
Continuous Torque Rating The torque rating at or below which the speed reducer should yield satisfactory life. Life is dependent on operating speed at this rating and the lubrication used in the speed reducer. Maximum reducer life will be achieved when operating at lower output RPM.

Definition? Intermittent Torque Rating (lb-in)
Intermittent Torque Rating The intermittent torque rating should not exceed 10% of the operating duty cycle. Continued use of the speed reducer at the intermittent rating may significantly shorten the life of the speed reducer.

Definition? Peak Torque Rating
Peak Torque Rating The peak torque rating is the rating at which continued use can cause catastrophic failure. This peak rating should be considered a worst-case shock load and should not be considered part of a normal operating cycle.

Definition? Shock Loads / Jerk


Definition? Overrunning Loads
Overrunning loads induce forces into the speed reducer that can significantly shorten life. Heco speed reducers are typically driven by hydraulic motors that are connected inline with hydraulic relief valves to relieve pressure spikes in the hydraulic systems. In overrunning load conditions speed reducers are back-driven into the hydraulic motors which turns the motors into hydraulic pumps that create hydraulic system pressure spikes. Typically hydraulic cross-port relief or counter balance valves will relieve these pressure spikes. Because of inefficiencies in the hydraulic motors being driven as pumps it can take 150% of the typical drive operating torque to back-drive a speed reducer/hydraulic motor and create enough pressure for the hydraulic system cross port relief or counter balance valves to react. This condition is prevalent in swing or slewing drives as well as ground power drives on mobile equipment.

Definition? Horsepower Rating
Horsepower Ratings In the case of high-speed operation typically seen in Industrial applications, Horsepower may be the limiting design factor not just torque. Higher horsepower applications are typically the combination of high speed and high torque. In this case horsepower rather than torque may determine the size of the Heco speed reducer that best fits the application. Auxiliary cooling may be required in high horsepower and high speed applications. Consult Heco on these applicat

Definition? Speed Ratings
Heco speed reducers can accept high RPM input. Applications requiring simultaneous high speed and high torque operation will have short design life. Applications requiring high speed and low torque duty cycles or low speed and high torque duty cycles will have extended reducer life.

Instructions? Lubrication Oil Recommendation
For maximum speed reducer life the recommended oil is SAE 85W-140 Multi-grade gear oil meeting API-GL5 and API-MT1 service. Alternate oil that will provide adequate speed reducer life is SAE 90W gear oil meeting API-GL5 and API-MT1 service. These oils should be readily available at your local automotive store or lubricant dealer. When using a Bearingless hydraulic motor or “Flow Through” lubrication where hydraulic oil from the hydraulic motor lubricates the speed reducer an ISO 68 hydraulic oil with EP1 additives and a minimum of 0.125% zinc anti-wear additive will provide adequate speed reducer life. Maximum oil temperature should not exceed 160 0F (70 0C) for continuous operation or 180 0F (80 0C) for intermittent operation. Consult Heco Gear for applications requiring use of non-petroleum based or fire retardant lubrication.

Product - Model 20 and Model 25 Shaft Seal History
The original Model 20 seal arrangement used a Quad Ring and Teflon back up ring for the pressure seal and a mechanical seal installed in the reverse direction as a “wiper” to keep external contamination away from the sealing area of the shaft. These seals were installed in a seal carrier that bolted to the front housing of the reducer. There was also an O ring that fit in an groove on the seal carrier that sealed the static interface between the seal carrier and the front housing of the reducer. The Quad Ring is Part #201170 (1 ea) The Teflon Back Up ring is Part #201190 (1 ea) The Wiper/Seal was Part #201500 (1 ea) not available and replaced fit and function by Part #251100 Two O rings to seal the body sections Part # 201010 This is seal kit SK20-4 When we brought out the Model 25 we did away with the Quad Ring shaft seal and Teflon back up ring and went to a mechanical type of shaft seal. These seals were tested by us at 100 PSI in the case of a reducer and went over 10,000,000 cycles without failure or significant shaft wear. We installed the same seal model in a seal carrier in two places, one seal facing inward to seal the gearbox and the second facing outward to act as a wiper. The pilot of the seal carrier had to be made larger to fit the larger opening in the reducer housing caused by the larger shaft bearings. There was also an O ring seal in a groove around this pilot area. The mechanical seals are Part # 251100 (2 ea) The O Ring is Part #251320 (1 ea) Two O rings to seal the body sections Part # 201010 This is seal kit SK25-1 When we introduced the Model 25 we also came out with a 20U seal kit that could be used to update existing Model 20 reducers to the Model 25 Seals. This kit requires a new seal carrier that has a pilot diameter that fits into the Model 20 and seal pockets that fit the new seals. There is also an O ring seal to seal between the pilot and the housing. The mechanical seals are Part #251100 (2 ea) The O Ring is Part #200690 (1 ea) The seal carrier is Part #200660 Two O rings to seal the body sections Part # 201010 This is seal kit SK20U

Product - Heco Model 16 Design Code Revision 7
Heco Model 16 Design Code Revision 7 Over the next several months Heco will be phasing in the new design code 7 on our Model 16 Series of reducers. This design change does not effect the fit or function of the reducer. We are changing the bearings in the planet carrier for longer planet bearing life. This, in turn, changes the planet gears, planet pins and planet carrier. These parts will not be individually interchangeable with the same parts from design code 6. A complete planet carrier assembly (part #15711) will be available and will fit design codes 6,5 and 4 reducers as a replacement part. The design code 7 planet carriers are also used on the 25D and 50D reducers. The design code with the new planet carrier on the 25D will be code 2. The design code with the new planet carrier on the 50D will be design code 7. The design code is found in the following position in the model code: 16FF105-7 25DCF1031-2 50DCF1031-7 52TCF10187-8 If you have questions about this change and any effect it will have on you or your applications please contact Darryl Fine (Ext.249) or Allen Rasmussen (Ext. 215). We will be happy to discuss this with you.
